T0 ALL WHOM IT'IVIAY CONCERN:

Be it known that I, HENRY R. RcBBNs, of the city and-county of Baltimore, and State of Maryland, have invented a new and improved Tobacco-Smoking Pipe; and I do hereby 'declare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawing, making a part of this specification, in which- My invention is vrepresented by a vertical section.

In thisinvention, the pipe, which is so sinall that it can readily be carried inthe pocket, is provided withl nn'improved apparatus for passhrg the smoke through water, and-for preventing the lwater'fi'orn escaping 4inte the stem or the bowl,.and is so constructed that it can be readily takeniapart for cleansing it. v

In the drawings, A represents thev stein, B the bowl,'and C a hollow glass vessel, of the form shown in the drawing. Across the centre oi" the vessel C'is a. foraminated metallic diaphragm or screen c, the perfora-l tions of which are very minute, being of n. size thatwill allow air, smol;e, &c., to pass through them slowly. under light pressure, but will not readilyallowwater to pass, except when impelled by'a considerable degreev of force. A tube, D, passes from near the bottom of the chamber within the vessel C up through the screen c, andthrough the roof of the vessel C, screwing into the bottom of the tobacco-bowl. It may be provided, both for ornament and oo nveniencein screwing or unscrewing it, withn milled nut, n, below the screen c, and it may bescrewed to or through the screen, so as to -attach the tube-screen and bowl together. v

`The smoke from the bowl B is drawn through the tube D to the ybottom ofthe chamber C, where it escapes into water,.with which the latter is filled nearlyup to the screen, and`then` rises in bubbles and passes through the perforations of 'the screen into the smoke-chamber in the upner part of the vessel G, whence it is drawn into the stem A. Y I If the pipe should be tipped over carelessly, or by any accident shaken so as toagitate the water below the screen, the latter will prevent the water from escaping from its proper place in the'vessel. It will also, during the process of smoking, canse theA smoke to rise through the water equally 'all around the central tube, and thus subjeetit` more completely tothe action ofthe liquids within the chamber.

The bowl B may be unserewed and removed, and the vessel G' may be formed of two parts screwed together by an nir-tight joint, s, by means of which the lower part or water-chamber may be unscrewed andremoved. YWhen this has been done, the screen c and tube D may be taken out, andthe stem A removed, and every part of th'e apparatus can be readily 'and perfectly washed and cleansed. i Having thus described my invention, whatI claimas new, and desire to secure by Letters Pat'e'nt, is 'Inl a smoking-pipe composed ofthe stem A, bowl B, tube D, and vessel C, I claimthe minutely-foraminated screen e, operating in eonnectian with the-tube D and vessel C, substantially as and' for the purpose specified. To the above specification of my improvement, I have signed my hand', this 26th dayof February, 1868. l
